NRF52 PM_EVT_ERROR_UNEXPECTED problem with connection

[Mario]

hello,

I used nrf52 and softdevice 2.0.1 and i have a big problem.

For some times the BT works perfectly but after i connect more then 4 devices for some reason the device return PM_EVT_ERROR_UNEXPECTED end stop working. The reset do not help i used sd_nvic_SystemReset() and NVIC_SystemReset() even i trya power off the BT module, but this error still happens

i received this error(PM_EVT_ERROR_UNEXPECTED) every time when i want to connect to a BT module to a phone.

Any ideas what cause this.

Inside the Peer Manager some times i see PDB_EVT_RAW_STORE_FAILED then PM_EVT_PEER_DATA_UPDATE_FAILED after that errors try to connect again and the PM_EVT_ERROR_UNEXPECTED comes.

-Yes i am not able to connect to any smart phone -Yes every second attempt to connect i received this error.

• I am using the ble_app_multirole_lesc example
• No, when i erase all everything is normal until for some reason the PM_EVT_ERROR_UNEXPECTED came the error came after BLE_GAP_EVT_CONN_PARAM_UPDATE
